Introduction The HB-150 Portable Brinell HardnessTester is designed following the Brinell hardness test method. The test force is controlled by a shear pin. After reading the diameter of the indention with the reading microscope, the Brinell hardness number can be obtained from the lookup table. The HB-150 Portable Pin Brinell Hardness Tester has two types of application: C clamp and hammer impact (see fig.1). It is capable of testing from small to very argespecimens.Itisespecially suitableforassemblies Fig. 1 Portable Brinell Hardness Tester inconve-nient to be takento the lab and not allowed to be cut. The test can be completed in any dire-ction to test the hardness of upper, lower and lateral part of the specimen. The test head itself can be used as a hammer impact tester. It can perform the testing by touching one side of the work piece. Its accuracy is much higher than any other type hammer impact tester. According to the similarity principle of Brinell hardness testing, with testing force of 1580kg, indenter diameter of 7.26mm, then F/D2 30. The test condition of the HB tester is equivalent to the standard Brinell Fig. 2 Hammer Impact Hardness Tester hardness test with 3000kgf and 10mm ball indenter. The HB-150 Portable Brinell Hardness Tester can be widely used to test the hardness of forgings, castings, steels, nonferrous metal and its alloy products, and to test the hardness of annealed, normalizing and temperedmechanical parts. Compared to the rebound type hardness tester, the Brinell tester has many advantages such as higher precision, fewer factors affecting accuracy and lower requirement on the surface roughness. The test result meets the requirements of most drawings without conversion and is more widely accepted in the international business. Used as a self-product the operation of HB-1 hammer impact Brinell hardness tester can be refered to hammer impact part of HB-150. 1

Principle and Structure (a) (b) 6 —— Test head (Indenter holder) 7 —— Rubber protective cap 8 —— Shear pin 9 —— Indenter 1 —— C clamp 2 —— Spiral tube 3 —— Thin screw 4 —— Handle 5 —— Anvil The structure of the instrument is shown in Fig.3. The instrument is composed of C Clamp, spriral tube, test head, thin screw, handle, anvil and the forve transmission system in the spiral tube. See Fig.3 (a). The sprial tube is used for clamping the specimen and the thin screw is for applying test force. See Fig.3 (b). The hammer impact Brinell hardness tester is composed of the test head which is taken off from the spiral tube, impact cylinder, holding handle and hammer. See Fig.2. The principle of the instrument and inside structure of the test head are shown in Fig.4. A shear pin is place in the horizontal hole on the test head. The indenter is pushed into the bottom hole and its top touches shear pin. The test head is placed into the spiral tube (C clamp) or impact cylinder (hammer impact). When the test force is applied on top of the test head, the force is transmitted to the indenter through the shear pin which presses indenter against the specimen. As soon as the test force reaches 1580kg, the shear pin is cut into three segments by the cutting system comprising the test head and the indenter. The excessive force will not be transmitted to the indenter as it withdraws into bottom hole of the test head,and a round indentation will remain on the surface of the specimen. The indentationdiameter is measured with a reading microscope, and the Brinell hardness number can be obtained from the lookup table. Fig. 4 Principe of the instrument 2
3. Technical Parameters Test force: 1580kg; Tolerance of test force: 0.5%; Accuracy: C clamp In accordance with ISO6506 Hammer impact 5% Indenter: Φ7.26mm steel spherical surface indenter (range: 100-400HB) Φ4.0mm carbide spherical surface indenter (Optional) (range: 400-650HB) Opening size (H D): 150mm 100mm Net weight: C clamp: 4.2kg Hammer impact: 0.8kg 4. Operation Instructions 4.1 Instructions for the C Clamp Tester The portable hardness testers includes the C Clamp, which is a kind of static test. 4.1.1 Indenter Selection. According to the expected hardness of the testing piece, choose the suitable indenter. When testing the softer metal with the hardness lower than 400HB, choose the steel spherical surface indenter with a diameter of 7.26mm; when testing hard steel materials with the hardness higher than 400HB, choose the carbide spherical surface indenter with a diameter of 4.0mm. 4.1.2 Anvil Selection. Choose an appropriate anvil to fit the shape and size of the specimen, and install it in the bottom of the C Clamp. The flat anvil is for flat blocks or sheets; the V anvil is for cylinders; the dome anvil is for curled sheets and pipes. The right anvil should provide a firm support for the specimen, and there should be no slipping or distortion when the force is applied. 4.1.3 Put a shear pin into the horizontal hole of the test head. Push the indenter into the bottom hole of the test head with the spherical surface out and make sure it contacts the shear pin. Cover the bottom of the test head with the rubber protective cap, in order that the cap contacts the bottom of the test head closely, the indenter should come out from the central hole of protective cap. The purposes of the cap are to protect the surface of the specimen and prevent shear pin from spattering. 4.1.4 Install the test head into the bottom of the spiral tube. 4.1.5 Check and confirm to bring the thin screw which is under the handle about 10-20mm up above the spiral tube. If not, operate according to Step 4.1.9. 4.1.6 Place the specimen in the opening of the C Clamp. Make sure the back of the specimen completely contacts the anvil, and the indenter is perpendicular to the tested surface of the specimen. Rotate the handle clockwise, drive the spiral tube down and clamp the tester on the specimen. After the indenter reaches the specimen, continue rotating the handle to drive the thin screw down until a breaking sound is heard, which means the shear pin is broken and the force application is completed. 4.1.7 Rotate the handle counterclockwise and raise the spiral tube. 4.1.8 Take out the test head from the lower part of the spiral tube and take off the rubber protective cap. Remove the broken shear pin and push the indenter out with the pin removal tool. 3
4.1.9 Hold the lower part of the spiral tube, rotate the handle counterclockwise and raise the thin screw up about 10-20mm above the spiral tube. Do make sure to raise the thin screw up after each test. 4.1.10 Use the reading microscope to read the indentation diameter in two perpendicular directions. Refer to Section 4.4 for the instructions of the reading microscope. 4.1.11 Check Appendix A or Appendix B with the average indentation diameter to get the Brinell hardness value. 4.2 Instructions for the Hammer Impact Tester The hammer impact tester does not include the C Clamp. It only includes the test head,impact cylinder, holding handle and hammer. The hardness testing by hammer impact tester is a kind of dynamic hardness testing. The hardness testing by hammer impact tester is a kind of dynamic hardness testing. 4.2.1 Put a shear pin into the horizontal hole of the test head. Push the indenter into the bottom hole of the test head with the spherical surface out and make sure it contacts the shear pin. 4.2.2 Place the test head into impact cylinder. 4.2.3 Put the handle on the specimen. Put the impact cylinder into the handle, and make sure the bottom of the impact cylinder rest firmly on the specimen. 4.2.4 Use the flat side of a 3 lb (1.5kg) hammer to apply a sharp blow on top of the test head. The shear pin must be broken at the first blow. If the pin is not broken, another blow must be applied in order to remove the pin, and the result must be ignored. 4.2.5 Take out the test head and remove the broken shear pin with the pin removal tool. Push the indenter outward off the hole of the shear pin. If the shear pin is not completely broken off, the test should be considered as invalid. Install a new shear pin and test again. Be sure to break off the shear pin completely. 4.2.6 The dynamic test with a bigger force may result in an elliptic indentation. The diameter of the indentation must be measured in at least two directions. Use the smallest diameter as the valid one to check Appendix C, D or E for the Brinell hardness value. 4.3 Usage of the Reading Microscope 4.3.1 Look into the ocular with enough light and turn the barrel dial to make the vertical lens line aligned with the “0” scale of the horizontal line. Meanwhile the long scale mark should rest on “0” scale of the barrel dial. 4.3.2Put the reading microscope on the test piece to locate the indentation in the centre of the viewing field of the microscope. Move the microscope to make the vertical line tangential to the left edge of the indentation. Press the bottom of the reading microscope, turn the barrel dial to make the vertical line tangential to the right edge of the indentation. 4.3.3Read the integral part (mm) of the indentation diameter from the horizontal scale mark, then read the 2-digit decimal part of the indentation diameter from the barrel dial. 4.3.3When the vertical line is aligned with the “0” scale mark of the horizontal line, but the “0” scale mark of the barrel dial is not aligned with the long scale mark, it means the microscope is inaccurate. Adjustment should be made as follow: a. Make the vertical lens line aligned with the “0” scale mark of the horizontal line. 4
b. Unscrew the three screws on the barrel dial. c. Make the “0” scale mark on the barrel dial exactly aligned with the long scale mark. d. Fasten the three screws. 5. Verification The Brinell standard hardness block is used to calibrate the Brinell tester. The test result on the test block should be close to the hardness of testing pieces. Impact on testing blocks by hardness tester and get indentation, measuring the average diameter value of indentation by microscope, then get the hardness value aftercheck appendix. The error of this tester is the difference between this value and the value of testing block. 6. Cautions and Tips 6.1 When testing with the C Clamp, the thin screw must be brought about 20mm up before testing. If not, the thin screw cannot drive the test force on the specimen and it may bedamaged. 6.2 Do not disassemble the spiral tube. The tester will be damaged permanently and the warranty will be void. 6.3 When the hardness of specimen is greater than 400HB, the carbide indenter must be used. 6.4 Indenters are normal wear items and are not covered by the warranty. The carbide indenter is more brittle and more easily broken than the steel indenter. 6.5 To protect the specimen surface from the impact cylinder, a cardboard with a hole bigger than indenter can be placed between the impact cylinder and the specimen. 6.6 Wear safety goggles and gloves to prevent possible injury.6. Cautions and Tips 7. Factors Affecting Testing Accuracy 7.1 Specimen Surface The surface of the specimen should be smooth and clean for the best accuracy. The rough surface makes the indentation edge blurry and affects the measurement of the indentation diameters which will increase the dispersity of the test result. The rough surface can also reduce the specimen’s resistance against the pressing indenter which will result in a lower Brinell hardness value. Use a sand paper or polish machine to polish the part to be tested for better accuracy.If the oxide coating, decarbonization layer, dust or dirt remains on the specimen surface,the hardness testing will be invalid. Remove those things before testing. 7.2 Supporting of the specimen Carefully clean the bearing surface of the specimen to ensure that the impurities or dirt like oxide coating, grease and dust can not be found between the back side of the specimen 5
and the supporting anvil. Choose the proper anvil, proper testing surface and the bearing surface to ensure that the specimen is firmly supported without sliding or deformation when the test force is applied. 7.3 Impact Effect of Hammer Impact Tester The specimen may move under the test force when the hammer impact tester is being used which will affect the testing result. When testing with the hammer impact hardness tester, loading and unloading of the test force is finished in an instant, and the dwell time of the greatest test force does not reach the set time of the ordinary Brinell hardness testing. This will affect the testing result. As above-mentioned, the operator should regularly make comparison tests with the standard Brinell hardness testers in order to ensure the accuracy of the testing result. The static (C Clamp) tester can be used as the comparison tester to verify the test result of the hammer impact hardness tester. The accuracy of the hammer impact Brinell hardness tester can be lowered by impact effect, so the prior selection should be static (C Clamp) testing if the specimen size allows. 8. Factors Affecting Testing Accuracy Brinell hardness test can reflect the average mechanical properties of a large region of the specimen, so there is a close relation between the Brinell hardness and other mechanical properties of materials, especially tensile strength. The approximate conversion equation is: σb K*HB in this equation: σb is the tensile strength value in MPa; K is a constant depending on the material. The tensile strength of materials can be obtained indirect by testing the Brinell hardness with its approximate value obtained by conversion, which is of great importance in practical production by both increasing work efficiency and saving material as well. The conversion of hardness-tensile strength of some metallic materials is shown below: Material Steel Brinell Hardness Value 125 175 175 Approximate Conversion σb 3.43HB (MPa) σb 3.63HB (MPa) Cast aluminum alloy σb 2.6HB (MPa) annealed brass, bronze Brass, bronze after being cold-processed σb 5.5HB (MPa) σb 4.0HB (MPa) 6
